Tip-Enhanced Raman (TERS): chemical imaging at the nanoscale

TERS brings you the best of both worlds: the chemical specificity of Raman spectroscopy with imaging at spatial resolution typically down to 10nm. This technique can be demonstrated on various samples ranging from 1D and 2D nanomaterials to DNA.

Not just TERS: high-speed TERS imaging!

HORIBA Scientific does not only provide TERS capable systems, nor do we only guaranty TERS enhancement when measuring at a single point. HORIBA Scientific is the first equipment manufacturer to guarantee TERS imaging capability and nano-resolution thanks to our STM-TERS tips, AFM-TERS tips and test samples.

High resonance-frequency scanner for high speed imaging and low sensitivity to acoustic vibrations. No need for active vibration isolation to obtain the true molecular resolution.

Visual confirmation of alignment on all channels.

Short path-length and closed-loop objective scanner laser alignment: brings higher throughput and outstanding long term stability, critical for TERS imaging.
